Charging
As with all Anton/Bauer chargers, charging with Tandem® 70 is fully
automatic.MountanyLogicSeries®batterytotheTandem® 70 and
it will automatically determine and execute the appropriate charge
routine.
Applications
The Tandem® 70 will charge any Anton/Bauer Logic Series® Gold
Mount®batteryincludingmodel:ProPac®,Trimpac®,DigitalProPac®,
DigitalTrimpac®,HyTRON®,andDIONIC®series.
NOTE: Anton/Bauer always recommends that each battery has its
own charge position. A battery can remain on an Anton/
Bauer charger indenitely.
TheTandem®70incorporatestheexclusiveInterActive®communication
betweenbatteryandcharger,whichallowsthechargertoidentifyany
Anton/Bauerbatteryattachedanddeterminetheprecisechargeroutine
forthatbatteryundertheprevailingconditions.
NOTE: Due to the specialized communications between the
charger and the battery, batteries without the Logic Series®
construction and communication capability (manufactured
by Anton/Bauer before 1989 as well as so-called “rebuilds”)
can not be charged with this charger. The InterActive®
communication of Logic Series® batteries is the key which
allows the Tandem® 70 to safely identify and address new style
and chemistry batteries as they are developed. Moreover, this
communication ensures that batteries contain the quality cells,
workmanship and safety of genuine Anton/Bauer products. If
a non-Logic Series® battery is placed on the charger, the red
and green LED indicators will ash alternately. This indication
means that the battery cannot communicate its identity to the
Tandem® 70 and is not charging. After 30 seconds of ashing
green and red LED’s, the red LED will remain on, indicating a
HOLD state.
WARNING: USE OF THIS CHARGER WITH ANY BATTERY NOT
MANUFACTURED BY ANTON/BAUER MAY RESULT
IN BATTERY DAMAGE AND CAUSE RISK OF FIRE OR
PERSONAL INJURY.
THREE STAGE CHARGING METHODOLOGY
Ingeneral,theTANDEM®70willdeliverathree stage charge routine
toeachbattery.
1. STAGE ONE will deliver a high rate charge matched to the
capabilitiesofthebattery(typicallyaoneortwohourrate,depending
onbatterytype).Duringthisstage,sevenseparatecutoffmethods
areinoperation,simultaneously,ensuringthefastest,safestcharge
forthatbattery:
TCO - TemperaturecutoffwhichstopstheStageonechargeprecisely
OPERATION
whenatemperatureindicativeoffullchargeisreached;
Dt/dT - A microprocessor based algorithm which measures a
riseintemperatureoveraspecictime,veryaccuratelyindicating
full charge.  This method is also the recommended method for
chargingNi-MHtechnology;
-∆V - Amethodtodeterminetheendofstageonechargingby
identifyingacharacteristic“reverseslope”ofaNi-Cdcell.Since
thischaracteristiccanbedisguisedbytheage,temperatureand
the number of the cells in a battery, it can never be employed
alone;
CCO -Thismethodrequirestheidenticationoftheparticularbattery
size(capacity)andchemistry,anexclusiveAnton/BauerLogicSeries®
feature.Thechargerdeterminesthemaximumcharge time forthe
particularbatteryandusesthisinformationtoensurethatovercharge
conditionsareavoided.
FUL - This determination is made when a fully charged DIGITAL
battery is returned to a charger within specied parameters of
time, temperature, and battery voltage.  The DIGITAL battery
communicatesitsfullychargedconditionandthechargerconrms
theparametersandimmediatelyindicatesafullychargedcondition,
withoutadditionalverication.
TEMPERATURE COMPENSATED VCO – For HyTRON™ series
ofbatteries.OptimizesVCOcutofftooperateonlywithincertain
temperatureparameters.
I-Min – for DIONIC batteries, a seventh cutoff method is
employed.ThebatteryischargedtospecicvoltageandI-Min
currentuntilfullchargeisreached.I-Ministhe“minimumcurrent”
owrequiredforpropercutoff.
2. STAGE TWO charging is a BALANCING or “equalize” mode which
calculates each battery pack type to offset any imbalance of the
battery’s cells, created by unequal self discharge or any capacity
mismatchoftheindividualcellsinthepack.Thisstagecanvaryin
durationfromzerotoasmuchas16hours,dependingonthecondition
of the battery. AbatterywilltypicallyleaveStageTwoin2-4 hours
underaverageoperatingconditions.
3. STAGE THREE Charging is the Anton/Bauer exclusive Lifesaver®
maintenancemode.Thispatentedpulseroutinekeepsbatteriesfully
charged,freefromself-discharge-indenitely-withoutdamagingheat
associatedwithaso-called“tricklecharge”.
NOTE: Anton/Bauer strongly recommends that batteries are kept
on a charger until ready for use. The Lifesaver® mode will
keep them 100% charged and ready for use.
